Summary: This study shows that the dehydrogenation activation energy of MgH2 can be lowered by incorporating ceria, but the ceria undergoes phase transformations during dehydrogenation. It also suggests that reduced cerium oxide phases may be mistaken as cerium hydrides, therefore the belief in CeH2 as an active catalyst in the MgH2/CeO2 hydrogen storage system needs further scrutiny.

Summary: The development of new heterogeneous Pt-containing catalysts has remained relevant over the past decades. This paper presents a method for producing metal-carbon composites, Pt1-xNix/CNF, with a tunable Pt/Ni ratio. The composites consist of Pt1-xNix (x = 0.0-1.0) nanoparticles embedded within a carbon nanofiber (CNF) structure. The synthesis involves the spontaneous disintegration of Pt1-xNix alloys in an ethylene-containing atmosphere, resulting in the formation of CNF. The study also investigates the impact of Ni content on the activity of Pt1-xNix alloys in ethylene decomposition, revealing an increase in efficiency with higher Ni concentration. Additionally, the synthesized Pt1-xNix/CNF composites exhibit superior activity compared to the Pt/Vulcan commercial catalyst in the electrochemical hydrogen evolution reaction.

Summary: Silver-gold nanocrystalline films were prepared on HDPE substrates using a novel process, and their structure, chemical composition, and biological properties were evaluated. The results showed that, in the short term, all silver-gold films had comparable bactericidal properties to silver-only films, and 65% silver films prepared with the new process conditions had comparable bacteriostatic abilities to silver-only films over a 7-day period. The inclusion of gold may have potential benefits for anti-inflammatory activity in future studies.

Summary: A lanthanum cerium fluoride abrasive was prepared using Ce-2(CO3)(3), La center dot Ce(CO3)(3), and NH4F raw materials at temperatures of 400-1050 degrees C. Various characterization techniques revealed that the materials consist of agglomerated irregular block-shaped particles with particle sizes in the micrometer range. The product was a mixture of cubic CeO2 and trigonal LaF3 below 850 degrees C, while above 900 degrees C, it became a mixture of cubic CeO2 and tetragonal LaOF. The material prepared at 900 degrees C showed potential as an abrasive for polishing optical glass surfaces, as it produced a clean and flat polishing surface with a moderate thickness difference before and after grinding.

Summary: In this study, a composite electrode composed of Ti/TiH2/beta-PbO2_Mn3O4@C was fabricated and investigated for zinc electrowinning. The composite electrode exhibited low overpotential, Tafel slope, icorr, and high voltage stability, outperforming most reported Ti-based PbO2 electrode materials. The excellent catalytic activity can be attributed to the low resistance and porous interlayer of TiH2 nanosheets, as well as the addition of Mn3O4@C micro-flakes to the active layer.
